Oracle EPM 11.1.2 (Hyperion)

I've done a few installs of 11.1.2 recently. One was a distributed install on windows (everything except Essbase, APS and EAS on the same server a second server housed the rest.) The other is a mixed environment where everything was on windows except essbase. So below are a few of my findings regarding 11.1.2.

1. Make sure DNS is working and that all servers can see each other by FQDN before attempting to install.
2. Ensure that the server can see it self by DNS name (not localhost).
3. On linux make sure SELINUX is disabled.

Failure to have either of these conditions met will cause all sorts of odd problems.

Now this may seem like common knowledge but in the case of my last two installs I was not involved with the setup of the hardware. In once instance I gave my specifications to an infrastructure team and trusted (by mistake) that they did things correctly. On the other I didn't think to check that the windows server and found out after the fact that the windows server thought its FQND resolved to the equilivent of 127.0.0.1 but in IPv6 (::1)
